of the soil level. The work was brought to a close September 5, 1936. 



In the latter part of August Dr. Roberts also investigated a site 

 near Kersey, Colo., where Folsom type objects were found by F. W. 

 Powars and his son Wayne, residents of Greeley. This location is 

 on a low terrace of the rolling terrain lying along the south side 

 of the South Platte River valley. Present evidence indicates that 

 it was a camp, but one occupied for a relatively short period of time. 

 Specimens obtained there represent a typical Folsom complex. They 

 are so similar to those from the Lindenmeier site that it is difficult 

 to distinguish between specimens from the two sites. Bones are 

 .'^carce, and those recovered are so fragmentary that they are valueless 

 for determining the species of the animals represented. 



After the completion of the Lindenmeier and Powars site investi- 

 gations Dr. Roberts proceeded to Sterling, Colo., where he visited 

 and inspected a number of sites in that vicinity. All proved to be 

 of more recent origin than the Folsom tyi)e niaterial. From Sterling 

 Dr. Roberts returned to Washington. The autumn months were 

 spent in the office working over the material obtained during the 

 summer's investigations. 



February 24 Dr. Roberts sailed for Cairo, Egypt, where he served 

 as one of two American experts at the International Conference of 

 Archeologists lield March 9 to 17, under the auspicxis of the Com- 

 mittee for Intellectual Cooperation of the League of Nations. As his 

 part of the agenda for the sessions. Dr. Roberts presented a paper 

 on the subject "The Material Organization of an Archeological 

 Mission." This included a discussion of the choice of personnel for 

 a field staff, the securing of equipment, the establishment of field 

 headquarters, and the general administration of such a project. At 

 the close of the conference he visited a number of sites in Egypt 

 and had an opportunity to study methods of excavation and general 

 archeological procedure as practiced in the Egyptian area. From 

 Egypt he wont to Greece, Italy, France, and England and studied 

 collections in the museums at Athens, Njiples, Rome, Paris, and 

 London. He returned to Washington April 24. 



On May 21 Dr. Roberts left Washington for Kingman, Ariz., 

 where he and C. W. Gilmore, curator of vertebrate paleontology, 

 United States National Museum, investigated a find of mastodon 

 bones and man-made objects. The deposit is located near a large 

 spring 24 miles west of Kingman. A week's study and excavation 

 demonstrated that the material Avas a secondary deposit, washed in 

 from surrounding slopes, and of no importance from the stand- 

 point of the association of man and extinct mammals. Dr. Roberts 

 left Kingman on June 2 for Denver, Colo., and Fort Collins. On 

 June 12 he resumed excavations at the Lindenmeier site. By the
